I like the game idea, and the graphics are really nice too!
The gameplay is a bit hard though. I don't know why there are 4 ghosts in the upper right corner when there are more than 4 ghosts flying around. I also don't really understand how to pick up/use items, I assume the bamboo clock that appears randomly is an item. Also, you can't pause with 'p' :(
All in all a cute little game! I tried to win multiple times but it was too hard with the many ghosts destroying stuff at the same time! I liked the simple controls though, the clear Menu is nice too, and the storyline for the game is awesome too :D
